...?Head Loss **Fluid** **Mechanics** Introduction **Fluid** flowing in pipes is usually turbulent. The flow is considered turbulent if the Reynolds value is greater than 4000. During the turbulent flow, the velocity distribution is relatively the same (or uniform) and the velocity profile is flatter in comparison to the laminar flow. It is important to note that there are pressure fluctuations and irregular velocity in turbulent flow. In turbulent flow, fluctuations in velocity influence the mean motion such that it causes additional shear resistance to the flow. The turbulent shear stress is composed of shear stress and viscous shear stress generated because of turbulence (Sawhney 2011, p629)....

...Laboratory Report: **Fluid** **Mechanics**— Verification of Bernoulli’s Equation The behavior of the laminar **fluid** motion along a converging-diverging tube of known cross-sectional area, at different flow rates, is investigated, and the mass as well as energy conservation laws are verified in this experiment. Another objective of performing it is to measure the loss of energy due to viscous resistance to the **fluid** the motion in case of higher flow rates. The results obtained from the experiment not only verify the basic laws and characteristics of a **fluid** in motion, but also determines the losses incurred in energy due to resistive forces. Introduction When a...

...into contact with air as they travel submerged underwater. When vessels travel at increased speeds on water, the influence of air affects the motion through inducing a lifting motion upon marine vessels. The lift normally occurs following substantial changes in speed and direction of flowing wind. While vessels might remain travelling at constant speeds, the speed of wind changes continuously. Achieving directional change in wind direction involves the **application** of a relative force upon the **fluid** (Faltinsen 2005). The lift becomes the force causing directional change in the wind flow, consequently resulting in development of lift-induced drag. The lifting produces **significant**...

...CIVL 3076 Environmental **Fluid** **Mechanics** Design of an Open Channel with Assessment of Pollution Transport Introduction An open channel is defined as aconduit in which a liquid flow with a free surface. The flow normally occurs under pressure as contrasted with liquid in a pipe, the liquid conveyed by an open channel exerts no pressure other than that caused by its own weight, and pressure of the atmosphere. The general theory applies to all liquids but since there are a few test data available on open-channel flow of liquids other than water at natural temperatures, it only applies to water. Open channels may be either artificial or natural. Natural water channels vary in size from tiny side-hill rivulets...

...means to trap inexhaustive potential in water resource. They facilitate large storage of water for future reuse. Dams are responsible for preserving wet lands, controlling sources of pollution, irrigation, electricity generation and recreation. However, it is a proven fact that dams are also responsible for causing low to high degree tremors, soil erosion and they render the site useless for future cultivation. Typical dam location can be represented as:

**Three** common types of dams are:
Site selection: Factors affecting reservoir/dam site selection is governed by the purposes for which the water resource is to be developed; these include:
1. Physical sustainability of available sites and terrain...

...Laboratory Report: **Fluid** **Mechanics**—Bernoulli’s Equation Using the conservation laws of streamline motion of **fluid**, we investigate the behavior of the **fluid** motion along a converging-diverging tube of known cross-sectional area, at different flow rates. The energy lost as a result of viscous resistance of the **fluid** the motion when the flow rate increases, may also be measured as Head Lost.
Introduction
When an incompressible **fluid** starts moving along streamlines, two basic laws get satisfied. One can use these two laws to check the behaviour of the dynamics of the **fluid**. Moreover, both these laws pertain to certain...

Determine viscous drag of bluff and streamlined bodies
Q3:
(a) Describe the terms skin friction drag and form drag.
On describing skin friction drag and form drag, one ought to comprehend the fundamental ideas accompanying the term ‘drag’. As introduced in **fluid** **mechanics**, ‘drag’ pertains to the force exerted on a material by the **fluid** through which it is transported, either co-currently or counter-currently. It is often referred to as a sort of friction made by the resistance of **fluid** against an object moving in it. In design calculations for a variety of structures, drag forces are considered to an appreciable extent to...
